Apache Camel: How to download multiple files from SFTP with Premove, Move and MoveFailed options?

I have two file names in following format:

Gontagrator_1.xml
Gontagrator_2.xml

As of now i am picking just Gontagrater_1.xml and rename it to processing and failed once done.

 + "&fileName=" + sftpFileName
            + "&preMove="+sftpFileName+".$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.processing"
            + "&move="+sftpFileName+".$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}"
            + "&moveFailed="+sftpFileName+".$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.failed"

Now Gontagrator_2 comes into picture. It is suggested to create separate routes for both.

Can we download both in one route and rename accordingly? If yes, what values i need to pass?

Update1: There are multiple files with different names but i need to use both above file names only

update 2: Whole from component is:

    "{{m.protocol}}://{{m.hostname}}{{t.directory}}"
            + "?username={{m.username}}"
            + "&password={{m.password}}"
            + "&download=true"
            + "&useList=false"
            + "&stepwise=false"
            + "&disconnect=true"
            + "&passiveMode=true"
            + "&reconnectDelay=10000"
            + "&bridgeErrorHandler=true"
            + "&delay=30000"
            //+ "&fileName=" + sftpFileName
            + "&include="+ sftpFileName
            + "&preMove=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.processing"
            + "&move=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}"
            + "&moveFailed=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.failed"
            + "&readLock=idempotent-changed"
            + "&idempotentRepository=#infinispan"
            + "&readLockRemoveOnCommit=true")
        .onException(GenericFileOperationFailedException.class)
            .onWhen(exchange -> { 
                    Throwable cause = exchange.getException(GenericFileOperationFailedException.class).getCause();
                    return (cause != null && cause.toString().equalsIgnoreCase("2: No such file"));
                }).handled(true)
                .logExhausted(true)
                .logExhaustedMessageHistory(true)
                 .log("Could not find file")
                .end()
        .log("Downloading xml file")
        //.to(archiveReceivedFile(sftpFileName))       
        .split(body().tokenizeXML("ERequest", "ERequests")).streaming()
            .inOnly(E_QUEUE)

Yes, you can download all files in one route.

You need to

  1. Remove fileName option (such that the route will pick all file)

  2. Use file expression language (file:onlyname) to refer to filename currently handled by Camel SFTP component

    + "&preMove=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.processing"
+ "&move=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}"
+ "&moveFailed=$simple{file:onlyname}.$simple{date:now:yyyy-MM-dd'T'hh-mm-ss}.failed"

  3. Use include option to control file to be picked up (REGEX to match file name pattern)

    + "&include=Gontagrator_(1|2)\.xml"
